Highest temperature in Amsterdam on June 7?

Prediction market odds on Polymarket reflect real-time aggregation of trader beliefs about Amsterdam's peak temperature on June 7, often diverging from traditional meteorological forecasts.

The current market price for each temperature outcome is visible in real time, allowing participants to enter or exit positions based on their own weather expectations and risk tolerance.

The market resolves on Jun 7, 2026, after the highest temperature in Amsterdam on June 7 has been recorded and verified. The outcome is determined by the official maximum temperature reading for that date from the designated meteorological authority or data source specified in the market rules. Once the actual temperature is confirmed, the winning outcome contract is settled at full value, and all other outcomes expire worthless. Traders who held shares in the correct temperature range or threshold receive their payout based on the number of shares held.

Several factors could shift market prices for Amsterdam's June 7 temperature. Major weather pattern changes—such as high-pressure systems moving into Western Europe or Atlantic storm systems—would alter trader expectations. Updated seasonal climate forecasts and long-range weather models released closer to the date carry significant weight. Real-time atmospheric conditions in early June, including jet stream positioning and sea-surface temperatures, influence near-term predictions. Historical temperature anomalies for that date and broader climate trends also inform market sentiment. As June 7 approaches, daily weather updates and official forecasts from meteorological services will likely drive trading activity and price adjustments.
